IMPROVEMENT IN MANUFACTU RING SHOES.

Specification forming part of Letters Patent N o. l 79,03 0, dated June 20, 1876; application filed A May 22, 1876.

To all whom it may concern Be it known that I, CARL H. KRIPPENDORF,

of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement 111 Machine-Sewed Boots and Shoes, of which the following is a specification p The object of my invention is to avoid the defects which accompany the use of the customary round needle in the sewing of boot and shoe soles to their uppers. The round holes made by such needles, if the stitches are sufficient] y short for a neat and permanent seam, operate to cut away so much of the leather as to endanger ripping in subsequent use; and it, to avoid this detect, the stitches are made long, the seam is both loose and unsightly, and the thread more liable to abate and fray out than where shorter stitches are represents part of a sole sewed on my plan. Fig. 2 shows a modification of my improvement. Fig. 3 represents the holes formed by the present or common mode of sewing. Fig. 4 represents the condition of such round holes, after having been stretched by the stitching.

A represents the under side of a shoe-sole sewed on my plan, B being the needle-holes and 0 the waxed thread forming the stitches.

'lhe needle-holes are oblong, and so presented A as to be comparatively narrow in the direction of the seam or line of stitching. -'Ihese holes may for this purpose have their longer diameters at right angles to the line of stitching, as at Fig. l, or somewhat oblique thereto, as in Fig. 2. v

I claim as new and of my invention- Ihe process of attaching the soles of bootsand shoes to the uppers by stitches from outside to inside'through holes whose greatest diameter is transverse to the line of the seam,

substantially as set forth.

In testimony of which invention I hereunto set my hand.
